Abstract :

The study, investigated the vehicular emissions on the ambient air quality of sections of Owerri municipal road by measuring the mean concentrations of CO, NO2, SO2, VOCs, NH3 and suspended particulate matter PM7, PM10 and TSP arising mainly from the activities of motor vehicles in the month of October, 2017. The sampled stations were Wetheral road, Okigwe road and Control Roundabout, which constitute one of the heaviest traffic congestion hotspots in the city. The sampling was carried out both in the morning and afternoon on four sampling stations and a control point and standard methods were adopted for field investigations. The levels of gaseous emissions from vehicular activities were sampled using a gas measuring meter of models BW Multi gas Monitor, Aeroqual Environmental gas Monitor and Aerocet 531 particle mass monitor for H2S, CO, NH3, CH4 , NO2, SO2, VOCS and Suspended particulate matter ranging from PM1 PM10 and TSP respectively. The result of the study showed that with the exception of NH3 3.889ppm and CO 7.944ppm other air pollutants NO2 0.108ppm , SO2 0.146ppm , VOCs 0.556ppm , PM7 0.088mg mm3 , PM10 0.140mg mm3 and TSP 0.216mg mm3 measured exceeded the concentration values stipulated by Federal Ministry of Environment FMEnv. , WHO World Health Organization and the United State Environmental Protection Agency USEPA . This could result to adverse environmental and health implications among the inhabitants. Regular air quality monitoring for better healthy living among residents of the study area is recommended.
